I have a 60GB 4G RWA iMod which has served me well for years. I have another iMod that is busted that needs to go back to Vinnie so I figured I'd send the 4G for a new battery. I'd also like to get him to put a higher capacity hard drive in it but he doesn't know whether there is one that will work in that model. Does anyone know of any HDDs that would work? Anyone tried putting a solid state drive in a 4G ipod?
